sound effects

The infamous gunshot effect thats heard on live DJ radio mixes (sounds downrange/ringout/mountains). Ive been searching all over the internet for this effect. I even took some gunshot effects and loaded them into Logic Pro which i do all my editing and mixing in and tweaked them around some and i have not be able to recreate that effect. Any help would be great!!!! I can send you a sample of this effect (you might be asking why dont i editing the effect out of the audio clip and i would do that but the fact that there is audio constantly behind it makes if somewhat difficult to near impossible). Again thanks for any help!
